  • Magnetically triggered on-board elapsed time indicator
    Patent number: 4392122
    Abstract: A vehicle such as a speedboat or racing car is equipped with a magnetic sensing coil (22) for producing electrical signals in response to detection of magnets disposed at one or more positions along the course. In the case of buoy-mounted markers, the magnets (26) may be mounted on certain of the buoys (10,13,14,17). The output from the sensing coil (22) is used to control on-board timing circuitry to enable the average vehicle speed over the course to be determined and displayed.
